Runtz, also known as "Runtz OG," is a rare type of  hybrid marijuana strain. Runtz is made by Cookies Fam by crossing  Zkittlez with Gelato and it is loved for its incredibly fruity flavor profile that smells just like a bag of the sugary candy we all know and love. Because of the rising popularity of this cannabis strain, it's no surprise Runtz was named Leafly Strain of the Year in 2020.
